Question

Define dalton’s atomic theory

Answer 1

$\textbf{Dalton's Atomic Theory :}$

→ Matter consists of individual atoms.

→ All the atoms of a given element have identical properties including identical mass. Atoms of different elements differ in mass.

→ Compounds are formed when atoms of different elements combined in a fixed ratio.

→ Chemical reactions involve reorganisation of atoms. These are neither created nor destroyed.

→ Dalton's atomic theory explain the law of combination.

Answer 2

Answer:

Acc. to it

☆Matter is made up of extremely small particles called atoms.

☆Atoms of same element are identical in size shape and atomic mass.

☆Atoms of different elements are different in all respect.

☆Atoms of same or different elements are combined together to form different compounds called molecules.

☆When atoms combined with each other to form molecules, they have simple or same multiple proportion.

Atoms can neither be created nor be destroyed.
